Wire Mesh Demister Pad Material, gas and liquid filter Mesh

What is a Demister?

DEMISTERs are essential in many process operations for the removal of entrained material in vapour flow. Demister ASIA’s Demisters and mist eliminators provide a wide range of solutions suitable for any application.

The principle of a Demister operation is based on having a large number of obstacles intercepting entrained droplets in a vapour flow. These obstacles must provide minimum drop in pressure over the removal system.

Wire Mesh Demister

DEMISTER Materials:

It can be made of various materials, depending on its use, and its major materials are as per the below:
1. SUS304, 304L, SUS316, 316L, MONEL
2. P.P (POLY PROPYLENE), P.E (POLY ETHYLENE), TEFLON
3.GLASS FIBER

Demister of wire mesh pad is also known as mist eliminators or sprays. This is a kind of high efficiency separation devices, used throughout all kinds of process industries, to remove liquid droplets from gas or vapor streams.

Wire mesh demister pads are used in chemical, petroleum, sulfate, medicine, light industry, metallurgy, machine, building, construction, aviation, shipping and environment protection. Demister pad is mainly used to eliminate streams with diameter of more than 3μm to 5μm.

Features of Wire Mesh Demister:

1. Simple structure with light weight.
2. Less pressure drop and big surface.
3. High demisting efficiency.
4. It is convenient for installation, operation and maintenance.
5. Long service life.

How a Demister Works:

Mist eliminators/ Demisters are fabricated from knitted materials with interlocking asymmetrical loops of metal or plastic with typical diameters of 0.1 – 0.3mm. By careful choice of wire diameter, DemisterASIA has produced demisters with extremely high free volumes (typically 98 – 99%) along with very high removal efficiency and low pressure drop.

Along with wire diameter and mesh density, another important parameter in design and operation of a demisters is the vapour velocity. This can be controlled by careful selection of the eliminator area. Optimal area will depend on operating temperature, pressure and pressure drop. Under normal operating conditions more than 99% removal efficiency can be achieved with a pressure drop of less than 250 Pascals.
